EMPROVEMENT IN LUBRICATORS.

Specifioation forming part of Letters Patent No. 50,719, dated Qctohel31, 1865.

T0 aZZ whom it may concern:

Beit known that I, S. E. KLEINSOHMIDT, of

Clevela-nd, in the county of Ouyahoga and State of Ohio, ha"e inventedcertain new and useful Improvement-s in Uil-Cups; andI do hereby declarethat the following is a full and com plete description of theconstruction and operation of the Same, reference being had to theaccompanying drawings, making a part of this speoification, in whiohFigure 1 is a perspeotxe view of the cup. Fig. 2 is a "ertical section.

Like letters of reference refer to 1ike parts in the views.

The oil-cup is made in two sections, A and B, formed as represented, andunited by a screwjoint at 1), or it may be otherwise c0n structed, so asto be adapted to the purpose for which it is designed. The enlarged porti0n C is an oil-chamber. From this chamber to the mouth A is an orifioeor opening, d.

Below the oil-chamber, and communioating with the maohinery to belubricated with oil, are orifices or openings 9 and h. The orfice 9 isextended up till near the top of the oilcharnber by a tube, g, which isone side of the opening d fron1 above. The orifices d, and h above andbelow the eha1nber extend through the plugs E and F of the faucets E andFwhen the faucets are ina certan position, as represented, and by meansof which the orifices are closed by turning the faucets in the ordinarymannen The practical benefits resulting from an oiloap constructed withtwo orifices below the oilchamber, one extending up, as descrbed, are asfo1lows: The oil-cup being in its position on the machine 0rsteam-chamber, the faucet F must be turned so as to close the orifices 9and h, shutting ofi the steam from below, and the aucet E turned so asto open the orfice d, when, by pouring the oil into the mouth A, it runsdown into the chamber 0, and when the required amount of oil is in thechamber, the faucet E must be turned, closing the orifice d.

The faucet F is then adjusted so as to open the orifices 7 and h, whenthe oil Wil1 run down the orifice 7zand the steam wi1l rise in theorifice and pass out at the top of the tube g, filling up the ohamber Oabove the oil.

In the first place, when the orifices 9 and h are first opened, thesteam will rise principally in the orifice g, for the oil Will berunning down in the orifice h, and the pressure of the oil wi1l preventthe steam from rushing up, as it does in the other orifice; and then thechamber above the oil is soon filled with steam, which oauses anequilibriurn, or the pressure of steam will oe equal, and the oil wl1run down by its own weight. The orfice g acts as a vent to relieve theorifice h from-the pressure of the steam, and thus allow the oil to passfreely down. \Vhere there is but one or ifice be1ow the chamber,when theoil runs down out of the chamber, a partial vacuum is formed above, andthe pressure of steam fron1 below being so great, it retards very 1nuchthe descent or flow of the oil, forcing it out more or 1ess through thejoints of the cup; but by the two orifices the charnber is filled Withsteam, the steam occupying the space occupied by the displace.

ment of the oil as it runs out. The displace ment of the oil being thusentirely taken up by steam risiug through the orifice g, causes the oilto flow most freely through the orifice h onto the mechanism.

What I claim as n1y rnprovement, and de S. E. KLEINSCHMIDT.
